Haha! Thanks.
The reason I made the keybinds to crossover by default is because of the way the NES controller is set up. On the console, you would be moving the piece with your left and rotating with your right and my brain just can't handle the opposite.

Does it also work if I use my left hand for rotating via Z and X and my right hand for the arrow keys. Or does it have some "hand crossover recognition" coded in that will blow the world up if someone does it wrong?
